Structural analysis / Functional groups in solids
Please contact Dr. Lawrence Alemany (firstname.lastname@example.org) for training.¬† Note that the theory behind and methodology for solid state NMR is very different from that for solution state NMR.¬† See, for example: http://en.wikipedia.org/wiki/Solid-state_nuclear_magnetic_resonance¬†¬†
Bruker 200 MHz spectrometer for magic angle spinning studies of most spin-1/2 nuclei in solids (most commonly 13C, 29Si, 31P, and 15N but not 1H or 19F) and specialized studies of solutions, including unusual 203Tl and 205Tl solution state NMR capability.¬†
As a practical matter, the spectrometer is ususually set up to do 13C solid state work with a probe designed for 4mm outer diameter rotors (sample volume about 75 microliters) capable of spinning up to 15 kHz.¬† With special 4mm rotors, significantly smaller samples can be studied.¬† Solid state work can also be done with a probe designed for 7mm outer diameter rotors (sample volume about 300 microliters) capable of spinning up to 7 kHz.¬† Coarse chunks of material cannot be studied in any rotor; the material would first have to be ground.¬† Only powders or other solids that can be uniformly packed in a rotor can be studied.¬† With any probe for solid state work, either 1H-X cross polarization or direct X-nucleus pulse experiments can be done.
Instrument Rules:¬† Specialized work takes priority on the 200 MHz NMR spectrometer.¬† Please contact Dr. Lawrence Alemany (email@example.com) to discuss your research needs and to schedule instrument time.
